Abstract

This invention relates to methods and apparatus for interfacing between computer channels and a Broadband Integrated Services Digital Network (B-ISDN) in order to allow such channels to communicate with a large number of other channels over the long distances and large bandwidth provided by B-ISDN. In a terminal adapter, channel addresses are translated into network addresses and channel format data is converted into B-ISDN format data in order to allow data messages between channels to be transmitted over the B-ISDN network.
